Last night my cubase crashed when bouncing down some audio. There was a high pitched sound from the monitors mso everything was turned off. Upon start up I had noticed the midi+audio drivers had gone.
This morning I downloaded driver, run the installer and restart. I have lost my audio, library +data drive. They are still shown in system profiler and have been verified+ repaired. But I have no access to them as I cant find them.

Please advise.

After a restart the drives came back. There is something seriosly wrong somewhere. Cubase is falling appart, mac cant find my scanner, lost audio/midi drivers.
I do regular maintance and run notron virus checker(not the latest).

Anyone got any ideas or know of any mac viruses at the mo?

There are no viruses for OS X, but Norton is known to cause problems.

Did not think mac had any viruses, but its only a matter of time.
Got it wrong I have intego virus barrier just in case.

Have you try to mount it?
May be it was taken off line.

Hi, I have seen a mounting option on disk utility, but don't know what it does.

If you can see the questionable HD on the left hand side with grayed-out name, hilite it and click mount (the blue button.)

Thanks azusa
